Application filed July 9, 1919 Serial No. 309,669.

T 0 all whom it may concern.

Be it known that 1, WILLIAM WENIGER, a subject of the King of Great Britain and Ireland, and a resident of Sheflield, county of York, England, have invented a certain new and useful Improvement in Anchors, of which the following is a specification.

This invention relates to a two-piece stockless anchor, that is to say, a stockless anchor in which the head and flukes are made in a single casting, and the shank and its trunnions made in a single piece or member.

The present invention consists essentially in the provision of flooding channels which permit the full and free ingress and egress of water, so that no sand, mud or other substance is allowed to settle between the shank and trunnions and the cores or to choke the action when the ship is riding at anchor during changing tides, a lifting shackle pivotally mounted in the trunnions of the shank and taking within the core of the head, and a readily removable locking device which takes up the back kick of the shank.

In order that the invention may be readily understood, reference is to be had to the following description and accompanying sheets of drawings, wherein Figure 1 is a side view of the improved anchor, partly in section.

Fig. 2 is an end view thereof, partly in section.

Fig. 3 is a plan view at crown, shank removed.

Fig. 4 is a plan view at head, shank removed.

Like letters of reference indicate corresponding parts in the several figures.

In carrying out the invention, the head a and flukes a are formed of a single casting, the flukes a being provided on both faces with gripping grooves a said grooves 66* being shallow at the edges of the flukes and gradually increasing in depth toward their ends where they die out to the surface. The head a is cored out at a", and the crown a of said head at at to receive the shank b and its trunnions 7), said shank and its trunnions being in one piece. The trunnions b, which are of a diameter less than the width of the cored out part a of the head a, turn on shoulders b in the head a, and flooding channels 0 arranged at right angles to the longitudinal axis of the trunnions are formed in Specification of Letters Patent.

Patented Dec. 14L, H m

the head a, said flooding channels 0 being extensions of the core of the head.

The locking device, which takes up the back kick of the shank b when the head a swings, and is positioned on said shank so as to clear the crown of said head, consists of two oblong keys (Z, of a length equal to the greater or end sides of the shank and arranged in said end sides, said keys (Z, whichare dovetailed on their inner sides, taking in dovetailed recesses d in the shank and being secured therein by a rivet d the removal of a head of which and the driving out of the rivet permits the withdrawal of the keys and the ready unshipping of the shank and its trunnions from the head when required.

WVithin a recess 6 in the trunnions b there is pivotally mounted by a pin 6 the boss sleeve 6 of a shackle 6, said shackle taking and swinging within the core a of the head.

Having now described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A stockless anchor including a one-piece shank having an integral portion forming trunnions at one end thereof, a lifting shackle attached to the said integral portion,

. a head cored out to provide flooding channels and to receive the shank, and locking elements carried by each side of the shank adjacent the crown of the head for holding the latter on the shank.

2. A stockless anchor including a one-piece shank having an integral enlarged portion at one end forming opposite trunnions and said enlarged integral portion being provided with a recess, a lifting shackle, means for pivotally holding the shackle in said recess, and a head cored out to receive said shank and trunnions, and means carried by the shank for holding the head in bearing engagement with the trunnions.

8. Stockless anchors with a one-piece shank and trunnions, and cored out shouldered head and crown for the reception of the shank and trunnions, characterized by a locking device consisting of dovetailed recesses in the side ends of the shank and located therein clear of the crown of the head, dovetailed wedges removably mounted in said dovetailed recesses and a rivet passed through said wedges and shank.

4. Stockless anchors with a one-piece shank and trunnions, and a cored out shouldered head and crown for the reception of the shank and trunnions, characterized by the combination therewith of a locking device consisting of dovetailed wedges removably fitting in dovetailed recesses in the end sides of the shank and a rivet for securing said wedges to said shank, a lifting shackle 10 pivotally mounted in a recess in the trunnions of said shank and taking within the cored out head, and oppositely disposed flooding channels arranged at right angles to the longitudinal axis of the trunnions, said flooding channels being extensions of the core of the head, the width of said core being greater than the diameter of said trunn'ions.

In testimony whereof I have afiixed my signature hereto this 12th day of June 1919.

WILLIAM WENIGER.
